Metals were 100% the problem.

Here is the issue that I found, and my 'so far' working remedy.

I added Pool Magnet and Metal Control to the water before shocking. Even when I get to the 'Best Guess Chart' Shock FC level. the Sequestering agent does not keep the Metals from falling out. So this is what has happened 2 years ago when I tried and the difference this year.

1. When the Metals fell out 2 years ago, I was going crazy between the forum and the pool store. The water was ugly, I was new to metals so I kept shocking and the water kept being ugly. I was also using Stabalized Chlorine which brought my CYA levels higher and required Higher FC levels. Then I learned about metals so I stopped shocking and began to treat the metals. Because I waited so long to begin treating the metals it took a long time to deal with metals, which means, I had my Chlorine levels very low for a long time, which in return caused Algea, which means I had to raise my FC's again and the viscious cycle began again.

2. This year I decided to conentrate on the water chemical balance and how it looks 2nd (What is on the inside is what counts). Small Adjustments I think is the key, and I still believe that putting the puck in the skimmer caused my metals to fall out the 2nd time, even though others don't agree. (See post).

If things change I'll repost.
